Monitoring of Ground Surface Displacement under Mining of the Sokolovo-Sarbai Deposit by the Radar Interferometry Method

Resumo

The ground surface displacement under mining of the Sokolovo-Sarbai iron ore deposit is measured using radar survey data obtained over the period from 2006 to 2016. The purpose of the research is to determine features of the process inside the displacement trough of the Sokolovskaya Mine under conditions of water-encroached loose formations. Using a series of ALOS Palsar and ALOS-2 satellite radar images, the vertical subsidence in the test area of the deposit is evaluated. The history and boundaries of displacements within the displacement trough, in pitwalls and in dump slopes are determined.
